abstract="The methodology of the National Truck Trip Information Survey conducted by the Center for National Truck Statistics of the University of Michigan Transportation Research Institute is described in this paper. The survey was conducted to achieve the two main goals of estimating the registered large truck population of the continental United States and providing detailed data on its annual mileage. Travel in the file can be cross-classified by road type, area type, and time of day, and broken down according to truck configuration, cargo body style, cargo type and weight, gross weight, number of axles, and driver characteristics. This type of detail is useful in risk assessment, because the risk of accident involvement depends on the operating environment as well as the physical characteristics of the truck.
